Hi!
Did you check the settings on the “Transport Advanced Options”-tab of the port? There you might see a block called “Transport Options”. Therein are the options for port-retrying. The port will not terminate to “suspended”-state before it has executed the given number of tries with the given interval. After this, the port will suspend and the failed message routing-process will kick in. In your case, as far as I can see, failed message routing may not even be nessecary (spelling on that one, anyone?). You might be able to utilize the “Backup Transport”.
Go through the port settings and fiddle around with that for a while and you might take a step in the right direction.
